Chevrette No. 1,753,233 where replenishment-is Referring to the drawing, Ihave shown dia 1 0 "effected by shifting boxes, yet" the invention is grammatically in Fig. 5 the general relation not limited to this arrangement, since it"may be which the auxiliary plate sustains to the other employed on the shifting box end of -a fancy or parts of the lay. v The lay wood '10 has secured. multicolor loom. A I thereto a metallic lay end 11 and theboxes 12 as r It is'a furtherand more specificobjectof my shown: are spaced slightly from the lay endto invention to provide a flat steel plate-having a provide room, for the auxiliary plate 13. The horizontal slot for the picker and suspended byparticular form of layillustrated in Fig s.,1, 3 and means ofscrews which extend into the lay end 4 is that which-may beffound in shuttle changer and is determined as to position-.byother screws looms. and hasthe usual reed 14 which may be' I 5 which extend through and are fastened to the, secured to the lay in any approved manner'and tion by spring 16. The box structure 12 may include top and bottom cells 17 and 18, respectively, the upper of which may benormally active to receive a shuttle during ordinary weaving- The lay end may include a wall 19 which is slotted as at 20 to receive a slide picker 21 propelled by a picker stick 22. A pivoted top or cover 23 for the upper box is shown inasmuch as this is a part of the shuttle changer loom to which I have applied my invention.

It is to be understood that the boxes canbe raised from the position shown in the drawing by means of a lifter rod 24, so that the upper box can receive a shuttle from the magazine not shown and the lower box can receive the depleted shuttle to be expelled at some later point in the cycle of the operation. Tongues 25 enter fixed grooved guides 26 to determine the plane of Q movement for the shuttle boxes. The guides 26 may be positioned relatively to the lay to give the desired motion to the shuttle boxes, as suggested in Colgan Patent No. 1,786,703. The binder acts yieldingly to push the shuttle back against the 7 plate 13.

Except for theplate 13 which has been men tioned the structure is substantially the same as that already existing andof'itself forms nopart of'my present invention. While the plate 13 has been described as part of a lay end'iound on shuttle changersyet it can also be used on the ordinary fancy or drop box looms with equal effect. 7 In Figs. 3 and 4 it is to be understood that the dot and dash line 27 defines a so-called reed line along which the shuttle is "to be moved. The race plate 'may extend along the dot and dash line 28 in these figures. These lines represent planes which serve to guide the. shuttle.

In carrying my invention into effect I provide means for positioning the plate 13 so that the same will assist in guiding the shuttle properly as the latter is picked. As shown herein I pro-' vide each of the corners. of the plate with holding screws 30 which are extended through the plate and threaded into the wall 19, as set forth more clearly in Fig. 3. Other screws 31 extend through wall 19 to serve as adjustable stops to position'the plate 13, and nuts 32 may be used tolock the adjusted settingoi" these last named screws. Al'- though I have shown but four pairs of holding and positioning screws, yet it is to be understood that ,I may employ as many asrare found necessary to position the plate, and they'may be disposed both above and below the picker slot 33 extending longitudinally through the plate as suggested by Fig. 4.

When assembling, the lay end may be secured to' the lay sword 35 and lay wood in any approved manner, after which the plate 13 maybe applied by means'of the screws 30,1;0 the wall 19 and the'adjustable positioning screws 31 change until the verticalforward face 36 of the plate is incorrect alignment with the feed 14;. Y The picker spindle 3'7 may be rendered adjustable to accommodate changing positions of the plate by a holder 38, 1,766,739. While this "holder is desirable, yetit is not 'necessary,' inasmuch as the picker spindle can be fixed in predetermined position and the plate moved so as to position the'rear wall of the shuttle box correctly with respect to such a position. During the rising and falling of the box the plate will remain at rest and the horizontal such as shown in Patent No.

partitions which define the upper and lower boxes will slide past the plate, the latter being at all times. in position to define the rear walls of the boxes. r

From the foregoing it will be seen that I have provided a lay. employing in its construction an auxiliary plate-to be adjusted withrespect to the reed line and serving as the rear walls for shifting shuttle boxes. By this construction it is not necessary to position the lay end accurately with respect to the reed line, so that a rigid and substantial connection can be made between the lay and the lay end which need not be disturbed, adjustments being made to afford the delicate setting desirable on the part of the rear wall of the shuttle'boxes by manipulating the holding and positioning screws to locate plate 13. Also, the binder, which need not be stationary as shown herein, pushes the shuttle against the plate in any position the latter may assume.

Having thus described my invention it will be seen that changes and modifications may be made therein by those skilled in the 'a'rt'without departing from the spirit and scope of" the invention and I do not wish to be limited to the details herein disclosed, but what I claim is:

' 1. In a loom lay, a batten, a lay end rigid with shuttle boxes, a shuttle guide between the lay and and shuttle boxes forming 'a wall of the latter,

and means tosecure'the guide to the lay end in any one'of a plurality 'of positions to vary the alignment of the shuttles in the boxes with re spect to the reed.

3; In a loom lay a batten having a reed, a lay' end rigid with respect to the batten, shifting shuttle boxes, a shuttle guide between the lay end and shuttle boxes forming a wall of the lattena binder to force a shuttle in one of the boxes against the guide, andmeans to secure theguide to the layv end in any one of aplurality of positions to vary the alignment of the shuttles in the boxes with respect to the reed. f

4. In a loom lay, a batten having a reed, a lay end rigid with respect to'the batten; shifting shuttle boxes, a'bin'de'r forming part of the boxes, a plate securedto the lay end'and located on that;

side of the boxes opposite thebinder, and means to give the plate any one of a plurality of settings relatively tothe lay-end to vary the position of I the shuttles in, the boxes relatively to the reed,

the binder movable to accommodate varying'posi tions of the plate.

5. In a loom lay, a batten having a reed alay end rigid with respect to the batten, shifting shuttle boxes, a plate on one side of the boxes forming one side thereof, stop elements interposed between the lay end and plate to give the latter a plurality of positions relatively to the lay end, and means to hold the plate in any of said positions with respect tothe lay end to align the shuttles in the boxes with the reed. 1

6. In aloom lay, shifting shuttle boxes, a batten, two attached members supported by the batten, one of said'members secured rigidly to the batten,

the other member forming part of the boxes and,

serving to guide a shuttle, positioning elements carried by one member to engage theother mem- 156 her to give said members a plurality of different relative positions, and holding elements connecting the members together.

7. In aloom lay operating with a picker, shifting shuttle boxes, a lay end fixed to the lay, a plate secured to the lay end and having a slot therein for the picker and forming part of the boxes, and holding and positioning means to locate the plate rigidly in any one of a plurality of positions on the lay end to vary the position of the shuttles in the boxes relatively to the lay.

8. In a loom lay having a reed thereon, a lay end fixed with respect to the lay, a shuttle box movable vertically with respect to the lay end, a

guide plate on the lay end forming the rear wall for the shuttle box, retaining; screws passing through the plate into the lay end to retain the plate in any one of a plurality of positions, and stop screws held in the lay end and capable of being moved to contact with the plate, said screws acting to hold the plate in alignment with the reed according to the position which the plate assumes. 1

9. In a loom,a lay, a reed to guide the shuttle,

a lay end forming part of the lay, a shuttle box,

movable vertically, and means on the lay end forming a shuttle compartment with theshuttlef box and movable CARL J. LINDEIGREN.
